I recently got a clutch change before winter on my 04 manual ~45k, its a stock to stock swap from a mechanic that has been so far reliable to me.

I usually drive in spurts of no more than 30 mins and did notice the clutch gets tougher to push and engagement does get higher over time. However, it was not significant enough for me to mention.

As the weather is getting warmer especially on this second 70* day I am noticing that the clutch is super stiff and and engament much higher! It also gets worse as I drive.

Ive checked my clutch fluid level and had it bled once already today, I unfortunately I'm not seeing any significant improvement.

Any ideas?

So before I get flamed, I did check other forum threads and did not see one that matched my issue.

 

could it be the master/slave cylinder?
and hows your clutch pedal holding up?
45k and new clutch? thats a bit odd.

 

yeap i know =(
the car was brought second hand at a price of free so i cant complain
the slave cylinder was also changed

the clutch pedal seems to not be the issue i went the local mazda meet any had someone more seasoned to confirm that i was fine.

would the clutch pedal harness change with heat!?

 

no, probably theres some air bubble in the line.
